Rating: 4 stars
A superb module for handling IPC in a straightforward, easy-to-understand, and very easy to use way. However, the documentation is very weak. There's enough documentation just to use it. The docs don't help you at all if you need to know more about how the underlying caches are used, where pitfalls might lie, creating a custom cache, etc.hanenkamp
